PHAZER

Use WASD or arrow keys to move. 

To finish every level (apart from the first one), you must repeatedly phaze into walls growing slightly smaller each time until you are the smallest size that you can be without disintegrating. You essentially go from being the biggest you can be, or "having everything", to being the smallest you can be, or "having nothing".

Note: There originally was a next level button at the end of every level but there was a problem with uploading the game to itch that made it not function. I couldn't find a solution within before this jam's deadline so I just removed the next level button.
